0? xD
OpenStudy (lgbasallote):
@rebeccaskell94 why'd you tell the correct answer o.O
OpenStudy (anonymous):
;D Because I am boss
OpenStudy (anonymous):
\[\lim_{x \rightarrow 7}\ln(5-3x)\]
OpenStudy (anonymous):
Well, that isn't 0...

darn ln :/
OpenStudy (anonymous):
then do yall have the answer...
@lgbasallote @rebeccaskell94
OpenStudy (lgbasallote):
im trying to remember how to do it...
OpenStudy (anonymous):
Well, I could be creative with an answer. But, in all honesty, I have no clue.
I mean...yeah. If you want to pass I am not the person to ask lol
OpenStudy (lgbasallote):

The above is the question??
OpenStudy (anonymous):
I think we can we use L Hospital rule here..
OpenStudy (lgbasallote):
\[\lim_{x \rightarrow 7} \left(\ln (5 - 3x) \right)\]
OpenStudy (lgbasallote):
but it's not in the form 0/0
OpenStudy (ash2326):
\[\lim_{x\to 7}\ln (5-3x)\]
put x=7
\[\ln(5-21)=\ln (-16)\]
log can't have a negative quantity inside, so limit doesn't exist

or \(\infty/\infty\)
OpenStudy (anonymous):
Really @ash2326 ??
OpenStudy (ash2326):
Yes, limit doesn't exist
OpenStudy (lgbasallote):
that's what i thought too..but there must be some simplification process to give a value to x
OpenStudy (lgbasallote):
i mean the limit
